Thank you for pointing out how incredibly complicated and thorny the issue is. >how much of that additional value should we... enable them to control? The answer may range from "none of it" all the way up to "all of it". Both extremes are wrong. I find myself frustrated that in the US at least (where top marginal income tax rates have been plummeting for the past 30+ years under the influence of neo-liberalism), far too many people are comfortable flirting with the "all of it" end of the spectrum.
